Hi!
A date as a primary key? Hummmmm.... never tried that, but my "not
good idea" buzzer is buzzing! :)
I suppose you could override something in the framework to
generate your own PKs (I know this is described somewhere, maybe in
the Apple Enterprise Objects guide), but I don't think it's legal to
set it manually. You shouldn't even have the diamond turned on on
that attribute.
Is there any serious reason to use date as a PK? Why can't you use
a normal PK? If you want to be sure that you don't have to equal
dates, just set a unique constraint on the database.

Hello;
One of the primary keys is a date field, how would the system set
this date?

I am using an oracle database. Anytime I attempt to insert a

I have set all of the primary key attributes before attempting to
insert the object. So I am kind of confused why I keep receiving
this message.
I don't understand what you mean by this. You have set the
primary keys manually on the object? If you did, than that's the
problem, that's the job of EOF, not yours. :)
